Transcript of Strep Throat

Scientific Names:
-Streptoccous pyogenes
-Streptococcal pharyngitis

Strep throat is caused by group A Streptococcus bacteria.

Common Names:
- Sore throat
- Strep throat
-The bacterium can be spread to cattle and then back to humans through raw milk as well as through contaminated food sources.
- Nasal discharge

-It takes 2-5 days for one to develop symptoms of strep.
- Infected cells begin to multiply
during incubation period.
Source of Pathogens
- Bacterial infection in throat and tonsils
-Innflammation in throat
- Causes swollen lymph nodes, sore throat, fever over 101 F, cold symptoms, difficulty swallowing

Specific Target: Throat
Source of Pathogens
-Severe and sudden sore throat without coughing, sneezing,or other cold symptoms
-White or yellow spots coating on the tonsils
-Red or dark red spots on roof of mouth
-Difficulty swallowing
Second line of Defense:Macrophages
Neutrophils ingest pathogen and become the antigen presenting cell which slows down the strep throat antigen.
First line of defense:Tonsils

Fight infection
The swollen tonsils begin to shrink back to normal size. The throat's redness should decrease and most symptoms should begin to slowly fade away. The bacteria is now fought off and the throat should be returning back to normal.
Third line of Defense
When the antigen is presented, a helper t-cell recognizes the dangers present. The t-cells inform the b-cells and the b-cells quickly begin to clone and specialize the antigen into plasma cells to produce antibodies. Cytokinesis, or the killer t-cells come and kill off the antigen. The regulatory t-cells inform the killer t-cells to stop, and the memory t and b cells take a small portion of the antigen to remember it by in order to active the antibodies the next time the strep pathogen is present.
Source of Pathogens
Non-Specific Defense
Specific Defense
Strep Throat
-Spread from person to person
- Direct contact with an open wound or sore that is infected
-Direct contact of another's mucous
Internal organ/system
Special Characteristics
If your body can not fight off the pathogen, then antibiotics are highly recommended.

Should not be contagious within 24hrs.
